requires static in Java
1. Introduction The requires static is used to define compile-time dependencies. The compile-time dependencies are required only during the compile time. Sometimes our code may have a dependency on another module, but only at the compile-time. The users of our code may not want to include the unwanted module on which our module depends. In…

requires transitive in java
1. Introduction In this tutorial, we’ll discuss the requires transitive. Before starting the discussion, let us discuss what is transitive dependency. Suppose there are three entities, A, B and C such that the following statements are correct: Then the functional dependency A -> C represents a transitive dependency. By default a transitive accessibility is not…

Accessibility of class with Java module
1. Introduction In this tutorial, we’ll discuss the accessibility of classes within a module. We’ll discuss different cases with the help of public class in a module and accessing this class from another module. For this tutorial, the two modules are moduleA and moduleB. The two packages are pack1 and pack2. pack1 is in moduleA…

Java module with example
1. Introduction In Java, a module is a unit of organization for Java code introduced in Java 9 as part of the Java Platform Module System (JPMS). It encapsulates a set of related packages and resources, providing a way to define dependencies and access controls between different parts of a Java application. Each module should…

Stream ofNullable method in Java
1. Introduction The signature of the method is: This method produces a sequential Stream comprising one element if it’s not null; otherwise, returns an empty Stream. This method is helpful in dealing with null values in the stream. The main advantage of this method is that can avoid NullPointerException and null checks everywhere. 2. Example…

Stream iterate method in Java
1. Introduction There are two overloaded versions of iterate method: 1. static <T> Stream<T> iterate(T seed, UnaryOperator<T> f) : This was available in Java 8. This method takes an initial value and a function that provides next value. This method returns an infinite sequential ordered Stream produced by iterative application of a function f to…

Stream dropWhile method in Java
1. Introduction The dropWhile method was added in Stream interface in Java 9. It is a default method. Following is the signature of dropWhile method: It is the opposite of takeWhile method. It drops elements instead of taking them as long as predicate returns true. Once predicate returns false then rest of the Stream will…

Stream takeWhile method in Java
1. Introduction The takewhile method was added in Stream interface in Java 9. takewhile is a default method in Stream interface. Following is the signature of takewhile: This method returns the stream of elements that matches the given predicate. If this stream is ordered, it returns a stream comprising the longest sequence of elements from…

Indify String Concatenation
1. Introduction This enhancement changed the static String-concatenation bytecode sequence generated by javac to use invokedynamic calls to JDK library functions. This will enable future optimizations of String concatenation without requiring further changes to the bytecode created by javac. The invokedynamic instruction simplifies and potentially improves implementations of compilers and runtime systems for dynamic languages…

useState hook
1. Introduction In React, the useState hook is a fundamental tool for managing state in functional components. It allows you to add state to your functional components without converting them into class components. useState hook enables you to declare state variables and update them within functional components. Here, state and count are state variables. Call…
